Alcohol septal ablation (ASA) is a minimally invasive heart procedure to treat hypertrophic cardiomyopathy (HCM). [1]It is a percutaneous, minimally invasive procedure performed by an interventional cardiologist to relieve symptoms and improve functional status in eligible patients with severely symptomatic HCM who meet strict clinical, anatomic and physiologic selection criteria.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Ordinarily, septal myectomies are performed only after attempts at treatment with medication fail. The choice between septal myectomy and alcohol ablation is a complex medical decision. [citation needed] Septal myectomy was established by Andrew G. Morrow in the 1960s. [3]
ablation equipment to destroy abnormal tissue; an electroanatomic mapping system that tracks and records the catheter position in 3D and associated electrical signals; ready access to cardiac medications such as adenosine, atropine, dopamine, and isoproterenol; ready access to an assortment of introducer sheaths and catheters
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
Ulrich Sigwart. Ulrich Sigwart (German: [ˈʊlʁɪç ˈziːkvaʁt]; born 9 March 1941) is a German retired cardiologist known for his pioneering role in the conception and clinical use of stents to keep blood vessels open, and introducing a non-surgical intervention, alcohol septal ablation for the treatment of hypertrophic obstructive cardiomyopathy.
The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children.It is similar to the previous atrial baffle used with a Senning procedure, the primary difference being that the Mustard uses a graft made of Dacron or pericardium, while the Senning uses native heart tissue.
[2] [3] The implantated valve is delivered via one of several access methods: transfemoral (in the upper leg), transapical (through the wall of the heart), subclavian (beneath the collar bone), direct aortic (through a minimally invasive surgical incision into the aorta), and transcaval (from a temporary hole in the aorta near the navel through ...
